Abstract Jinchang Mining edge technology enterprises, because enterprises established as a city, known as "the motherland are the nickel," is a typical resource-based industrial city, Gansu province is one of the three solid waste, the solid waste varieties, produce quantity Big.

Jinchangyuan Mine is a famous resource-based industrial and mining city, which is known as the “nickel capital of the motherlandâ€. It is one of the three solid waste discharge areas in Gansu Province, with many solid waste varieties and large production capacity. . As a typical resource-based city, the rigid constraints of resources and environment have increasingly become the biggest factors restricting Jinchang's economic and social development. If we do not change the way of development, the environment will be difficult to bear, resources will be difficult to sustain, and sustainable development will not be discussed.
After years of exploration and practice, Jinchang has constructed a circular industrial system pattern of “enterprise small cycle, industrial cycle, regional large cycleâ€. The enterprise small cycle focuses on reduction, energy conservation and emission reduction, clean production, extension of the industrial chain, and comprehensive utilization of resources; industry circulation is focused on resource reuse, focusing on the reuse of key enterprise wastes, local investment Transforming, turning waste into treasure, and realizing the symbiosis development of related industries; the regional big cycle is to use the park as a platform to extend the industrial chain through recycling and realize the maximization of resource utilization benefits.
The level of resource utilization has increased significantly. It has successively implemented 756 scientific and technological projects such as ultra-fine nickel oxide, electrowinning cobalt production technology development and lithium-ion battery in key enterprises, and achieved 206 scientific and technological achievements, including 76 major scientific and technological achievements, nickel-based alloy, cobalt oxide and printing. 28 new materials such as nickel mesh, nano-nickel powder and ultra-fine copper powder were included in China's high-tech product catalogue, and the world's largest nickel sulfate production line and the largest nickel chloride, nickel oxynitride and cobalt in the country were built. Salt series production line. Jinchuan Group has successively developed dozens of New Products such as nickel-cobalt precious metal powder materials, electronic grade nickel oxide, pure phase cobalt carbonate for lithium ion batteries, high-purity nickel, high-purity cathode copper and fine selenium, and gradually entered new non-ferrous metals. In the new fields of materials and calendering, raw material chemicals, titanium metallurgy and titanium chemicals, nickel carbonyl and carbonyl iron, solar energy and secondary battery research, nickel-copper-cobalt calendering processing capacity is continuously enhanced. At present, the city has 14 core technologies that have reached the world's advanced level and have independent intellectual property rights in the fields of nickel-cobalt-platinum metal mining, selection, smelting and related new materials. It has the world's leading industrialization capability, and the Jinchuan Resources Comprehensive Utilization Project has won The first prize of the National Science and Technology Progress Award, Jinchuan Group Company won the “China Industrial Awardâ€, the highest comprehensive national industrial award.
